The number of protons, neutrons and electrons for each atom increases as you go down a group. Hydrogen is the lightest element as it has the fewest sub-atomic particles.

What is periodic in the periodic table?
The modern periodic table is modified form of the mossleys periodic table,which was yet modifiied form of the mendileevs periodic table,which was based on the principle-atomic mass is the periodic function of the elements.Mossley changed the periodicity of elements to be the periodic functions of their atomic numbers.hence in the modern periodic table we can find,the repeatation of certain properties of elements after definite intervals and hence the periodic table has groups and periods the elements inside which,are similar.this is possible because across a period electrons increase by 1,keeping shells sama,and down a group,outer electrons remain same,but shells increase by1.
When you go down the periodic table what happens to the electronegativity?
Increase -tac
Which periatic table cannot be broken down into simpler substance?
All of the elements of the periodic table cannot be broken down into simpler substances.
What happens to the atomic mass of elements as you move across and down the periodic table?
the choices are: A. They increase from left to right and top to bottom. B. They increase from left to right and bottom to top. C. They increase from right to left and top to bottom. D. They increase from right to left and bottom to top.
What type of elements tend to have low ionization energies?
The elements in the lower right part of the Periodic Table. Cs, Fr, Ra, Ba etc.
Do elements on the periodic table increase in electronegitivity as you go left to right or up and down?
Electronegativity increases as we move from left to right on the periodic table.
Why do elements increase in size as you move down the periodic table?
Down the group, atomic radius increases. This is due to increase in number of shells.
How are the size of the elements effected on the periodic table?
Atomic size increase down the group and decreases across the period.

Which way does electron shells increase on the periodic table?
The number of shells in periodic table increase down the group, i.e., vertically.
What happens to elements as you move down the periodic table?
they do something
What is found on the periodic table and cant be broken down?
Elements are what make up the Periodic Table; they also cannot be broken down into smaller substances.
What is the difference3 between a family of elements and elements in the same period?
a family is a column of elements a period is a row of elements
When you go down the periodic table what happens to the electronegativity?
Increase -tac
What kind of elements are in the periodic table?
The horizontal rows of elements on the periodic table of elements. Periods gain one proton and one electron as you read the table from left to right.
When moving down the middle of the periodic table is there an increase in nonreactive atoms?
yes
How many of the purpose of the periodic table?
the reason why we have the periodic table is to be able know the universal elements easier than writing down the wholle word.
